Speaking to Daily Mail, Bobby Brown has claimed his relationship with Whitney Houston drove him into a nightmare of drug addiction.

In his upcoming autobiography, Bobby Brown: The Truth, the Whole Truth and Nothing But, the singer — who was married to Whitney from 1992 to 2006 — lifts the lid on his relationship with the ‘I Will Always Love You’ hit maker.

He writes: “I never used cocaine until after I met Whitney. Before then, I had experimented with other drugs, but marijuana was my drug of choice.

“At one point in my life, I used drugs uncontrollably. I was using everything I could get my hands on, from cocaine to heroin, weed and cooked cocaine.”

Bobby — who has a 15-year-old daughter, Bobbi, with Whitney — also believes his marriage to the superstar was destined to fail from the start. “It was doomed from the very beginning,” he says in the book, which is due out next month. “Within the first year we separated, with several more to follow.

“I think we got married for all the wrong reasons. Now, I realize Whitney had a different agenda than I did when we got married . . . I believe her agenda was to clean up her image, while mine was to be loved and have children.

“Whitney was under a lot of pressure. The media was accusing her of having a bisexual relationship with her assistant, Robin Crawford.
